APPARATUS FOR IMPROVING THE FIRE-TEST OIT-PETROLEUM AND FOR LEACHING OTHER OILS.

SPECIFICATION forming part of Letters Patent No. 297,603, dated April 29, 1884.

To all whom it may conce/w:

Be it known thatI, JOHN B. HUsroN, of Cleveland, iu the county of Cuyahoga and State of Ohio, have invented a new and Improved Apparatus for Improving-thc Fire-- Test of Oil and for Bleaching Animal and Vegetable Oils, of 'which the following is a speciiication. ,y

rIhis apparatus consists of a cylinder or vessel having a series of chambers, one above the other, the iloors ofwhich are perforated, with the exception of the lowest one. By the side of said vessel is placed a large air pipe having communications with the upper part of the said chambers. Within said pipe a steam-pipe and an oil-pipe are placed, the

steam-pipe having connections with the lower part of said chambers, while the oil-pipeleads up to and communicates witha low chamber in the`top of the aforesaid chambered vessel. The steam-pipe warms the air in the air-pipe and thiswarms the oil before they enter the said vessel. The branches of the steam-pipe are provided with stop-cocks. Outlet-pipes are provided to each chamber, opposite to the steam and air pipes, for the escape of the va- Ihis comprises the arrangement for treatment of petroleum products;` For the bleaching purpose a box for containing the bleaching material is placed near the base of the said air-pipe, to whichit is connected by a short pipe. On opposite side of'said box .is' placed an air-blower for the purpose of forcing the fumes or gases from the said box into the aforesaid chambered vessel. From the top of the said vessel a pipe leads back to said blower. This is for returning the said v bleaching-gases to the blower and using them repeatedly.

AThe iigure in the accompanying drawing is a side elevation of my improved apparatus, partly in section. if

A is a cylindrical vessel, (a cylindrical form is preferable,) standing on endl, and is of such dimensions as will be most convenient for working. It lis divided into three or more compartments by iioors a a, which are perforated with a large number of small perforations, the object of which will be hereinafter shown. By the side of said vessel A stands a large pipe, B, closed at the bottom, and is Y Application lled June 9, 1883. (No model.)

connected by pipes b b with the several compartments near their top part. Within the said pipe B is placed a steam-pipe, C,having branch connections c c, provided with stopcacks c', connecting it with the several compartments in said vessel A a little above the several iioors. Within said pipe B is also placed a pipe, D, passing up by the side of said pipe C, and through top of pipe B, and into the-top of said'vessel A, and terminating with a flaring mouth in the middle of a low chamber near the upper perforatedvfloor.l I`o opposite sides of said vessel A are attached pipes E, located a short distance above each floor, designed for the escape of the vapors, which may be collected and condensed, if desired. To the bottom of the vessel A is attached a pipe, F, provided with a trap for the withdrawal of the condensed steam and oil.

The operation of this is as follows; The oil oughly separate the light-er elements from the,

oil. The several compartments in the vessel A serve to divide the particles successively, so that all are affected and all the ylighter vapors are fully eliminated.

Near the base of pipe B is placeda box, G, having a' pipe-connection, g, therewith, and near said box is placed a blower, H, connected by a pipe, h', to the box G, at opposite end to pipe g, and the said blower is also connected by a pipe, I, to the top of vessel A. The purpose of the blower is to force the air into the said vessel A. In the box G is to be placed a bleaching material when the apparatus is used for bleaching, and the steam is omitted and stop-cocks closed, the blast of air, forcing bleaching element into the several chambers and mingling with the particles of oil, bleaches and puries them. rIhe oils to be 'to be treated passes through the pipe D from Steam is roo bleached are fed through the pipe D in the same manner as that for improving. The blast of air is used in both cases.

Having described my invention, I claim as follows:

The apparatus for improving the lire-test of oils and for bleaching animal and vegetable oils by a direct contact of live steam to petroleum or direct Contact of bleaching material to animal or vegetable oils in a finely-divided condition, consisting of a vessel, A, divided by perforated iioors a into two or more compartments, an air-pipe, B, connected to the upper part ofsaid compartments by pipes b b, and inclosing a steam-pipe, C, connected to lower part of said compartments by pipes c c, and also inclosing oil-pipe D, connected to top chamber of vessel A, the vapor-escape pipes E, a box, G, for containing bleaching` material, and a blower, H, connected through said box to air-pipe B and pipe I With top of vessel A, substantially as described.
